CAR-COUPLING.

' SPECIFICATION forming part of Letters Patent No. 433,453, dated August5, 1890. Application filed April 11, 1890. Serial No. 347,552. (Nomodel.)

To all whom t may concern:

Be it known that I, GEORGE H. DOUGALL, Sr., a citizen of the UnitedStates,residing at New Orleans, parish of Orleans, State of Louislana,have invented a new and useful Automatic Oar-Coupler Especially forCoupling Cars, of which the following is a specication.

Figure l of the drawings represents a lonl gitudinal vertical section ofthe two opposing draw-heads, showing my invention applied thereto andone end of the coupling-'link in position preparatory to being' coupledto the opposite draw-head. Fig. 2 represents a horizontal section of oneof the draw-heads with one end ofthe link coupled thereto; Fig. 3, anend View thereof.

The present invention has relation to certain new and usefulimprovements in automatic car-couplers, and the object thereof is toprovide means that will facilitate the coupling of the draw-heads of theopposing cars, and when so coupled will be effectually and securely heldtogether until uncoupled by the trainmemand its automatic actionrendered more certain and effective.

Thev above-mentioned objects'are obtained by the constructionsubstantially as shown iu the drawings, and hereinafter described andclaimed.

In the accompanying drawings, A B represent the two opposing draw-heads,which are coupled together by the usual link C, said draw-heads having avertical hole a, through which passes a tapering key D. The purpose ofthis key is to retain the coupling-link in a horizontal position orangle against the coupling-pin, and also prevent the link from beingpushed back into the opening b of the draw-head, The key is providedwith a head c for connecting thereto in any suitable manner a chain orbell-crank, in the former instance the key hanging from its connectionson the side of the car when not in use.

Upon the upper side or top of the drawhead is suitably connected abracket E, which serves as a guide for a coupling-pin, the same beingformed in two sections F G. The upper section F passes down through anopening in the draw-head, and has a shoulder CZ, to form a stop andsupport therefor to limit its vertical movement. The section F has ashank H, which extends up through an opening in the bracket E, and lisguided thereby in its vertical movement, a chain or bellcrank beingconnected to the upper end of the shank, the latter being preferablysquare or flat-sided, and the hole in the bracket to correspond, so thatthe liability of the twisting of the shank is avoided.

The lower section G of the coupling-pin is pivoted at e to the sectionF, and to allow of the free movement of the pivoted section, when forcedback by the end of the couplinglink, a spacef is provided immediatelyabove theopening h and on line with hole a, so that the section G can beelevated sufficiently to admit of the end of the coupling-link passingbeyond it, when `the section G will drop down by gravity to an uprightposition to engage with the link.

Previous to the coupling of the cars the link should be connected to oneof the draw-heads and the key and coupling-pin in position, as shown, indraw-head A and the key removed in the draw-head B, and replaced afterthe coupling-pin engages the link, in the manner above described.

rlhe operation is very simple, and further description is thereforedeemed unnecessary.

The draw-head may be connected to the car by bolt g, or by any otherwell-known and preferred manner.

Having now fully described my invention,

what I claim as new, and desire to secure by.

Letters Patent, is-

l. In a car-coupler, the combination, with the draw-head having thebracket E, of the coupling-pin consisting of the pivoted section G andthe section F, having shank H extending up through a hole in the bracketto form a guide therefor, and a suitable coupling-link to engage withthe pin, substantially as and for the purpose set forth.

2. In a car-coupler, the combination, with the draw-head having thebracket E, and the coupling-pin consisting of the pivoted section G andthe section F, with shank H, of the key D and a suitable coupling-link,substantially as and for the purpose described.
